After the upgrade of conductor, the routers are stuck in "Connected" state and not moving to "Running" state.

SSR Routers stuck in Connected state after conductor upgrade.

This generally happens incase of connectivity issue between router and conductor. Verify the salt connectivity between the routers and conductor. If the basic connectivity has no issues, check for any error message in /var/log/salt/minion log path.

One such possible error is

"Error: Could not update package 128T-minion-connector"

Check "dnf list 128T-minion-connector", If incase any recent version of package is available.

Check by running command "dnf update 128T-minion-connector" and see if it works.

If it does not work and command completes with "Nothing to do" .

In such cases it is assumed that there is inconsistency in rpm metadata cache locally.

Run below commands to update yum/dnf cache

# dnf clean all

#dnf makecache
